Over-crowding at the weekend's new East London site resulted in an early closure and an investigation has started to try and find out why.
In its third statement since the premature shutdown, Bloc organisers said they would welcome input from ticket-buyers as they investigate what happened on Friday.
The statement read: "We wanted to reiterate that we have launched an investigation into the events of Friday night. To that end we have opened an email address to which we would like you to submit any information you think may be relevant.
"We are keen to hear from you so we can build the most accurate picture and report of what happened. As ever, you guys are at the heart of what we do so please drop us a line with any comments on email@example.com".
After five years of being staged at holiday parks, the event was run at East London's new Pleasure Gardens complex this year. Shortly after midnight on the first day of the event, police recommended a shutdown to avoid putting festival-goers in danger.
Some reports say there were problems with the CrowdSurge ticketing system the festival used or that the set up of the site wasn't able to accommodate the festival's 15,000 capacity.
Information on refunds is expected in due course.
